From my Linux Mint operating system, how do I install/dual-boot this Ubuntu OS which is downloaded as a .iso file?
So that it comes up as an option to boot into when I first turn on my computer. Thanks.

In order to make an Ubuntu live USB for installing Ubuntu, use UNetbootin (Windows<=Windows 7/Mac/Linux/Linux Mint Software Manager). The flash drive you use should be 2GB or larger and formatted to FAT32. UNetbootin will automatically format the USB flash drive to FAT32 if it is not already formatted to FAT32. In either case the formatting procedure will delete all of the files that are already on the flash drive.
It is very important to verify that the device that you are installing the Ubuntu live USB to is indeed your flash drive, so that you don't overwrite any of your system or personal files which may make your operating system unbootable. In Linux Mint you can find the device name of the flash drive using the Disks application. In the picture below the name of the flash drive is
The Ubuntu live USB flash drive that you make this way will be bootable on PC computers. In order to enable your computer to boot from the USB flash drive, you must enter your BIOS menu by pressing one of these keys: Delete, F2 or F10 as soon as the motherboard splash screen appears when the computer is booting. In the BIOS menu, you need to change the boot order so that the USB flash drive, which is usually called USB-HDD in newer computers, is the first entry in the boot sequence, and then save your new BIOS settings and exit the BIOS setup.
I usually go the tried and true method: Burn to a CD and pop in drive, reboot, change the boot order in the BIOS to boot from CD FIRST, reboot a second time and install.
This may be your only option. I know Ubuntu has an app called Wubi that can install from within a OS but its windows specific.
So in your case, crack into a terminal
or you can get a copy of something like k3b or Brasero and burn through a GUI.
EDIT: Also, verify the checksum of the ISO before you burn. Will save you MANY headaches if you somehow got a bad ISO.
